Green Tea VPN Tutorial: Common Connection Issues and Fixes
Lead: "Won't connect," "connected but no internet," and "suddenly slow" — these three are the most common help requests to Green Tea VPN support. This tutorial breaks them down into reusable troubleshooting paths so you can solve most issues yourself before contacting support.
The core idea of troubleshooting is "from simple to complex, from local to whole": confirm the basics first, then move to servers, version, and system settings. With the right order, problems are often located in minutes.
1. Won't Connect: Check Basics
"Won't connect" is vague; first distinguish "cannot establish a connection" from "connected but cannot access." The former relates to network, account, or version; the latter to DNS or servers.
Step one, confirm your local network by opening an ordinary site. Step two, check whether your account is expired and the client is the latest. Step three, switch to a different region's server to rule out a single-server fault.
If all is normal but it still fails, check your system time — a drift over a few minutes breaks the encryption handshake, the most easily overlooked cause.
2. Connected but No Internet: DNS & Servers
Connected but no web access usually relates to DNS. After the tunnel is up, DNS requests should also go through it, but some systems' DNS cache or config can interfere. Restart the client, or switch to the built-in DNS in settings.
Another common cause is a server under high load. Switching to a lighter-load server often restores access immediately. The client shows live load; pick a green-status server.
| Symptom | Likely Cause | First Check |
|---|---|---|
| Won't connect at all | Network/version/time | Network & system time |
| Connected, no internet | DNS/server load | Switch server/built-in DNS |
| Suddenly slow | Line congestion/load | Speed test & switch |
3. Slow Speed: Locate the Bottleneck
First judge whether it is "line congestion" or "local network." Use the smart speed test to check real-time latency. If all servers are high, the issue is local; if only the current server is high, switching fixes it.
During evening peaks (19:00–23:00), international lines congest and slowdown is normal. Choosing a low-latency nearby server often beats clinging to a popular one.
| Time | Congestion | Suggested Server |
|---|---|---|
| Daytime | Low | Any fast server |
| Evening peak | High | Nearby low-load server |
| Late night | Low | Distant server OK |
A user hit a sudden slowdown at evening peak; following the guide, he switched to a Hong Kong server via smart speed test, and download speed recovered from 12 Mbps to 58 Mbps. This shows most "slow" issues are solved by switching servers, not reinstalling. More free VPN questions are in the FAQ.
4. Conclusion
Most connection issues follow a clear path: check network, version, time, switch servers, switch DNS. Walk through in order and most problems resolve on their own; if not, contact support with the specific symptom for faster help.
